If you plan to stay in the cryptocurrency world for the next three years and aspire to treat trading as a second career, you must read these 10 ironclad rules. They are valuable insights for making a living through trading, and I suggest saving them!

1. Suppose you have 1 million. After a 100% return, your assets will reach 2 million. If you then lose 50%, your assets will revert to 1 million. Clearly, losing 50% is easier than earning 100%.

2. If you have 1 million, after a 10% increase on the first day, your assets will be 1.1 million. Then, after a 10% drop the next day, your assets will be reduced to 990,000. Conversely, if you lose 10% on the first day and gain 10% the next day, your assets will still be 990,000. If you have 1 million, earn 40% in the first year, lose 20% in the second year, earn 40% in the third year, lose 20% in the fourth year, earn 40% in the fifth year, and lose 20% in the sixth year, your assets will be 1.405 million, and the annualized return over six years will only be 5.83%, which is even lower than the 5-year treasury bond coupon rate.

3. If you have 1 million, if you can earn 1% daily and exit, after 250 days, your assets can reach 12.032 million; after 500 days, your assets will reach 14.5 million.

4. If you have 1 million, if you achieve a 200% return continuously for 5 years, your assets will reach 243 million after 5 years, but such high returns are hard to sustain.

5. If you have 1 million and hope to reach 10 million in ten years, 100 million in twenty years, and 1 billion in thirty years, then you need to achieve an annualized return of 25.89%.

6. Suppose you bought a certain cryptocurrency at 10 yuan with an investment of 10,000 yuan, and now it has dropped to 5 yuan. If you invest another 10,000 yuan, your average cost will decrease to 6.67 yuan, not the 7.5 yuan you might expect.

7. If you have 1 million and invest in a certain cryptocurrency with a 10% profit, when you decide to sell, you can retain 100,000 yuan in market value. This way, your holding cost will return to zero, allowing you to hold onto it long-term without pressure. If you are extremely optimistic about this cryptocurrency and keep 200,000 yuan in market value, you'll find your profit rises from 10% to 100%. However, don't be complacent, because if this cryptocurrency drops by 50% later, you may still incur losses.

8. A sharp drop is a litmus test for quality cryptocurrencies. If the market crashes and your cryptocurrency only dips slightly, it’s clear that the market maker is defending the price, and you can hold onto such cryptocurrencies with confidence; you will surely gain rewards.
